Congratulations to Rick Thompson and his colleagues on their recent receipt of a NIH grant to serve as the Data Coordinating Center for the MISTIE III stroke trial. MISTIE III is 5-year, international, multi-center phase III clinical trial that will investigate a novel minimally invasive neurosurgical technique for the treatment of intracerebral hemorrhage (ICH). There are currently no proven therapies for ICH, a condition with a one-year mortality rate greater than 40%. In addition, long-term functional impairment for ICH is substantially greater than with ischemic stroke, resulting in disastrous personal, social and economic consequences that impact approximately 100,000 Americans each year. The primary hypothesis of this trial is that rapid reduction of ICH blood clot volume within the first 3 to 4 days post-onset via minimally invasive surgery will result in better functional outcomes in recovering patients when compared to ICH clot resolution through standard of care medical management.

Congratulations also to Rick’s Clinical and Biostatistics collaborators on the project: Daniel Hanley, Professor of Neurology and the Principal Investigator of the Clinical Coordinating Center for MISTIE III, Michael Rosenblum,Gayane Yenokyan, Marie Diener-West, Carol Thompson, Andre Hackman, and Josh Betz.

We are very pleased to announce that Ciprian Crainiceanu has been promoted to Professor. Ciprian’s accomplishments were outstandingly lauded by those who wrote letters to review his academic record, a panel truly notable as luminaries in our field. Among many impacts of the prolific body of work Ciprian has led, his scholarship is making it possible to conduct rigorous analyses of data acquired through imaging, wearable computing, and other data-intensive measurement modalities with sufficient computational efficiency that the methods can be feasibly applied in epidemiological cohort studies -- a true breakthrough for leveraging these data to improve the public health. Moreover he has contributed to discovery regarding a host of specific health problems, from mapping brain function in older adults with Alzheimer’s disease, to delineating neural changes and brain lesion processes accompanying multiple sclerosis, to characterizing sleep quality and determining its effects on health outcomes, to understanding patterns of activity in older adults using accelerometers, to quantifying measurement error in observational studies. Finally he is an exceptionally energetic and effective teacher and mentor and a valued colleague. Ciprian makes us better in so many tangible and intangible ways. Congratulations, Ciprian!

Faculty members Brian Caffo, Ciprian Crainiceanu, and Martin Lindquist have written a nice editorial for the Huffington Post on theneed for statisticians in neuroimaging.

July 2013

The July 22 issue of the New York Times highlights recent work by O. Joseph Bienvenu et al, with statistical contributions from Biostatistics PhD candidate Jonathan Gellar, ScM alumnus Ben Althouse, and Assistant Scientist Elizabeth Colantuoni. It is estimated that 35% of patients surviving ICU stays for critical illness present with PTSD symptoms within the first two years after the ICU stay. The NYT article provides several disturbing personal accounts of PTSD symptoms along with highlighting the need for physical AND mental health evaluations in ICU survivors.

Congratulations to PhD candidate Jonathan Gellar, who won the best student paper award at the Statistical Modeling Society's 28th International Workshop on Statistical Modeling (IWSM). Our department was also represented by ScM graduate and incoming PhD candidate Elizabeth Sweeney and PhD candidate Jiawei Bai, both of whom gave excellent presentations and made a huge impression on the organizers. The IWSM is one of Europe's most important statistics conferences and was attended by more than 200 researchers from the USA, Germany, Italy, Spain, Belgium, Netherlands, Portugal, France, Ireland, Brazil, Chile, and the UK.

Congratulations to Assistant Professor Jeff Leek, who has been awarded an NIH R01 grant to develop methods for characterizing and addressing biological and technical variation in RNA sequencing (RNA-seq) data, and software by which to implement them. RNA seq has become the method of choice for making measurements of gene expression. However statistical methods are needed to ensure the interpretability of these data. Dr. Leek’s proposal will tackle three key challenges: to estimate and remove hidden artifacts in the data, to create methods that can account for differential expression but do not require annotation or genome assembly, and to develop methods to correct ambiguous, variable and unidentifiable assemblies. Dr. Leek’s work will create a modular, integrated pipeline which promises to increase researchers’ capacity to exploit RNA seq data to discover the molecular architecture of diseases and develop prognostic signatures through which at-risk patients can be identified and treated.

Assistant Scientist Gayane Yenkoyan, in collaboration with lead author Mark Riddle and others, has been selected to receive the American Academy of Child and Adolescent Psychiatry's Elaine Schlosser Lewis Award for best paper on ADHD appearing in the Journal of the American Academy of Child and Adolescent Psychiatry over the past year.

Congratulations to Associate Professor Martin Lindquist, who has been awarded an NIH R01 grant to develop a basic framework for causal inference in functional magnetic resonance imaging (fMRI) research. Researchers use techniques such as fMRI to study effects of external stimuli on human brain function and causal relations among different brain regions. The concern with causal issues has prompted much work; however, in this work associations frequently have been interpreted as effects, often inappropriately. This is a major problem for a field where causation occupies center stage. In addition to the development of a rigorous causal framework fMRI research, Dr. Lindquist's work will also extend the statistical literature on mediation, leading to a body of methods for causal inference with high dimensional data.

May 2013

Congratulations to Marie Diener-West, who has been named by the Student Assembly for the 2013 Golden Apple Award for teaching excellence, large class size.

The citation also noted Dr. Salzberg’s public advocacy for greater sharing of data and against software and gene patents. More information may be found here. Dr. Salzberg is a jointly-appointed professor in the department as well as Professor of Medicine.

Congratulations to this year's recipients of the Helen Abbey Award for Excellence in Teaching: Kirsten Lum, Therri Usher, and George Wu.

Congratulations to Postdoctoral Fellow Sherri Rose, whose article "Mortality risk score prediction in an elderly population using machine learning” has been selected as the Editor's Choice in the current issue of theAmerican Journal of Epidemiology (AJE). In the article, SuperLearner--an ensemble approach that produces a prediction function from among multiple candidates--was found to outperform other algorithms for predicting mortality in older adults.

Congratulations to Associate Professor Ingo Ruczinski, his mentee Shelley Herbrich, and their colleagues, who have just published work challenging the standard paradigm for analyzing proteomic experiments based on isobaric labeling methods with reporter fragment ions. Such experiments typically include a common reference standard, in which protein relative abundance is estimated and combined across multiple experiments ("masterpool"). The new work shows that using such a reference standard is counterproductive - one can obtain more precise estimates of protein relative abundance by processing the available biological data instead through a random intercept model. You can check it out in the December, 2012 issue of the Journal of Proteome Research.

Kudos to Biostatistics student Hilary Parker, whose data-informed reflections on the demise in popularity of her name have been picked up by New York Magazine. In the piece, originally posted on her blog, Hilary compares the precipitous decline in the frequency of "Hilary" as a choice of baby name occurring in 1993 to other female names most dramatically declining in popularity in the US over the last 132 years. You can check out her findings here. Congratulations, Hilary!

Congratulations to Professor Constantine Frangakis, who has been awarded a four-year NIH R01 grant to develop designs and methods to accurately estimate survival in programs such a PEPFAR. Dropout poses a severe challenge for such estimation. Professor Frangakis has previously developed designs in which a subset of those dropping out are targeted and intensively pursued, termed "double sampling" designs. The current work will develop methods to estimate survival from an existing double sampling design as well as create new double-sampling designs optimizing accuracy subject to cost constraints and that best target clinical goals. Professor Frangakis will lead a team of collaborators including former student Ming An in the work.

In work recently appearing in the Journal of the American Statistical Association(107:1297-1309, 2012) Associate Professor Martin Lindquist has published methodology allowing for the application of structural equations models (SEMs) with functional data analysis. The work specifically evaluates mediation, that is, a treatment-to-outcome causal effect mechanism that operates partly through intermediate variables. Dr. Lindquist's work allows a mediating variable to be a continuous function rather than a scalar measure and supplies sufficient conditions for identifying the average causal effects of the functional mediators using the extended SEM. The work has potential to illuminate brain connectivity, as a specific example, and to the best of our knowledge, provides the first extension of SEM and application of causal inference to the FDA framework

Professor Mei-Cheng Wang and student Shanshan Li have developed a new tool for evaluating the predictive accuracy of biomarkers using tree-based classification rules. Their research extends the conceptual framework, methods and properties of Receiver Operating Curve (ROC) analysis from the assessment of single markers at a time to a multivariate marker setting. The new procedures are useful for evaluating predictive accuracy based on different choices of markers as well as for evaluating different and-or combinations in classifiers. The work recently appeared in Biometrics.

We are pleased to announce that Brian Caffo has been promoted to the rank of Professor. Our department celebrates Brian’s many research achievements, excellence as an educator, generous contributions to better the School, profession, and all of us, and outstanding recognition for the same. Congratulations, Brian: we're very proud of you!
